Here's your first peek at Chris Evans in this summer's Captain America: The First Avenger, and not only are we excited about the film itself, but Evans' muscles are also a big selling point!

Costume designer Anna Sheppard revealed that it took the star 25 minutes to get into the suit, and even though he could have done it with a wardrobe assistant, he preferred to slip into the getup on his own. She explains, "He likes to do it all by himself. I think it helps him feel like a super hero."
